In an effort to build beautiful, functional pieces using cheap or free materials, DIY builder James Higginson recently constructed a gorgeous wall out of recycled scaffolding boards that were past their prime. The boards he found were split in places and were no longer useful as scaffolding, but for interior use they were perfect. As he explains on his blog, Higginson cut them and sanded them down, and treated them for termites before installing them. The resulting wall looks rustic, and it adds warmth to a room for little cost.
